PATENT SILAS B. TERRY, OF TERRYVKILLE, CONNECTICUT, ASSIGNOR TO SILAS B. TERRY, JR., OF SAME PLACE.

MACHINE FOR MAKING PAPER BOXES.

Specification forming part of Letters Patent No. 25.373, dated September G, 135.9.

F0 a/ZZ whom 13 may concern: Y

Be it known that I, SILAs B. TERRY, of Terryville, in the county of Litchfield and State of Connecticut, have invented a new and useful Machine for Manufacturing Faper Boxes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure I is a front view of my invention; Fig. 2, a transverse vertical section of the same, taken in the line .r Fig. 3. Fig. 3 is a plan or top view of the same; Fig. et, a longitudinal section of the shell or case which contains the cylindrical head to which the end pieces of the boxes are attached; g/ y, Fig. 3, indicates the plane of section; Fig. 5, a perspective view of the device by which the side strips of the boxes are covered; Figs.- 6 and 7, transverse section of the same, taken in the line-z a, Fig. 5. Fig. 8 are views of the several parts of a box that are operated on by this invention; Fig. 9, a vertical central section of a paper box such as are constructed by my invention. This invention relates to a machine that is designed to facilitate the manufacture of circular paper boxes; and it consists in the einployment or use of a rotating clamp, gage, or`

socket, discharging-ring, pressure-roller, and guide, the above parts being arranged substantially as hereinafter described, and used in connection with a folding device, whereby the manufacture of the above-named boxes is greatly expedited and the work done in a perfect manner.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a base or platform, to which four uprights, a b c d, are secured. The uprights a b form supports for a mandrel, B, which has a crank', e, on its outer end and a circular disk, f, on its inner end, said disk having spurs g attached to its face side, as shown clearly in Fig. at. The mandrel B is allowed to rotate and also to slide longitudinally in its bearings. The uprights c d form supports for a mandrel, C, the inner end ot' which has a cylindrical head, D, attached, with spurs h on its face or end, and pins z' prol,jecting from its periphery to serve as stops to a ring or band, E, which is tted loosely on the head D. The upper end ofthe support d is provided with a cylindrical socket, F, in which the head D is allowed to slide freely. and through the socket F screws or pins j pass, the use of which will be presently explained. The mandrel C is also allowed to turn freely and slide longitudinally in its bearings.

To the front part of the base or platform A an upright, Zz, is attached, and on the upper end of this platform an inclined plate, G, is secured. The plate G has a flange, Z, turned up at one edge, and a ledge, m. is secured to the plate 'parallel with the ledge, as shown clearly in Figs. I and 8. i I-I is a lever which is itted on a fulcrum, n, on the base or platform. rThis lever is connected at one end by a link, o, and lever o to a coi1-spring iitted in a box, p, on the platform. In Fig. I the coil-spring is shown by dotted lines.

To the upper surface of the base or platform A an upright, I, is attached. This upright has a bar, K, titted on an axis, q, in its upper part. In the'front end of this bar K a pressure-roller, L, is placed. The periphery of this roller is provided with a iiange, i', and a recess, s, as shown clearly in Figs. l and 4. The back end of the bar K has a weight attached, said weight having a tendency to keep the front end of the bar elevated. An upright, M, is attached to the front part of the base or platform, said upright having a ledge or shoulder, t, on its upper surface to serve as a stop for lever II.

N, Figs. 5, 6, and 7, represents a metal plate attached to a base, O. This plate has a ledge, a, secured longitudinally to it, and a bar, v, is attached to the front part of plate N by pivot-s w w, as shown clearly in Fig. 5, said pivot-s permitting the bar o to fold over on plate N, as shown in Fig. 7.

The operation is as follows: The circular pieces of pasteboard a (see Fig. 8) which form the end pieces of the boxes are previously out out by any suitable machine, and the long rectangular strips of pasteboard b as well as the white strip of thin paper C are also previously cut by machinery. The above parts constitute the stock which my invention works up. The circular pieces of pasteboard c are covered at one side with white paper, this work being also previously done. The operator iirst throws back the lever H so that it will bear against the stopt, and then throws back the mandrel C so that the head D will be within the socket F, as shown in black, Fig. 4t. A piece of pasteboard, a/is then inserted in the socket F, the inner diameter of which is just the size to receive it. (See Fig. 4.) rlhe pasteboard c is placed against the face or end of the head D, and the disk f is then shoved against the pusteboard, which is consequently secured by the spurs f/ 71` between the head and disk. The lever H is then elevated above the ledge or shoulder t, and theeoil-spring in the boxp forces the head D out from the socket F, as shown in black in Figs. l and 3 and in blue in the en larged section, Fig. 4. The operator now takes a stiip, c', ot thin white vpaper and places it onthc plate N, one edge being against the ledge u. This paper c is then pasted on its upper surfacc,and astrip, b', of pasteboard is placed on the paper c directly over the bar r. lThe bar 'U is then turned over, as shown in Fig. 7,'and the pasteboard strip Zi will be covered with the strips c ot' white paper, a projecting edge or margin ot' the latter being left. The covered pasteboard strip b is then placed on the inclined plate G, the ring E on the head D being shoved back so that it bears Yagainst the pins or stops 1'.. The bar K is then turned down and the roller L bears on the head D. The operator then. turns the mandrel B by hand and the circular pasteboard a is rotated and the covered pasteboard strip Z/ drawn between the roller L and the head D, the ilange fr of roller L turning the margin of the thin strip of paper c over the edge of the circular piece ot pasteboard a, and thereby connecting the strip b' with the circular piece c, the latter forming the top or bottom ofthe box and the former part ot its side, each box being 'formed ot' two parts constructed preeisely similar, one portion, which forms the lid orf cover, fitting over a strip, au, pasted within the other portion, which forms the lower part of the box. (See Fig. 9.) The roller L while performing its work is pressed down on the head D by hand.

From the above description it will be seen that the invention connects the circular parts c with the strips D', said parts forming the tops and bottoms and sides of the boxes, the remaining work-such as the past-ing of the strip cX in one part-being done by hand, as also the covering of the boxes, if desired,with colored paper. When the parts c. are connected with the parts Z/ ot' the box, the lever H and mandrel C are forced back by hand. the head D passing within the socket F, and the band E, being arrested by the screws or stopsj, serves to force the part ofthe boxjust formed ott from the head D. The band E therefore serves as adischarging device as well as a gage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The pressure-roller L in connection with the rotating clamp formed of the head D and diskf, arranged substantiallyas and for thc purpose set forth.

2. In combination with the pressure-roller L, head D, and diskf, the ring or band E, provided with the pins or strips fi, the socket F, provided with the screws or pins j. and the guide-plate G, arranged for joint operation as and for the purpose described.

3; The arrangement ofthe pressure-lever H and sliding mandrels B C', for the purpose speciiied.

4. The ei'nployment or use of the folding device, formed ot' the plate N, provided wit-h the ledge u and the pivoted bar c, when said folding device is used in connection with the pressure-roller L, rotating head D, and disk f, i'or the purpose set forth.
